Doomsday clock moves forward 2 minutes
The Bulletin of the Atomic Scientists (BAS) is moving the minute hand of the Doomsday Clock today from seven to five minutes to midnight. view more (2007-01-18)
Research leads to healthful strategies for re-setting the body's clock
Everyone is equipped with a biological clock, a region in the brain the size of a corn kernel, which dictates our sleep-wake cycles, and plays a major role in our physical and mental health. view more (2006-03-23)
Circadian surprise: A heat sensor for body-clock synchronization
New research on the fruit-fly brain points to a possible mechanism by which temperature influences the body clock, according to scientists from Queen Mary, University of London. view more (2009-10-30)
Optical Atomic Clock: A long look at the captured atoms
Optical clocks might become the atomic clocks of the future. Their "pendulum", i.e. the regular oscillation process which each clock needs, is an oscillation in the range of the visible light. view more (2008-02-06)
Researchers propose new molecule to explain circadian clock
The internal clock in living beings that regulates sleeping and waking patterns -- usually called the circadian clock -- has often befuddled scientists due to its mysterious time delays. Molecular interactions that regulate the circadian clock happen within milliseconds, yet the body clock resets about every 24 hours. view more (2007-08-28)
More evidence mammals, fruit flies share make-up on function of biological clocks
A study by researchers at New York University and the University of London offers additional evidence that mammals and fruit flies share a common genetic makeup that determines the function of their internal biological clocks. The study appears in the latest issue of Current Biology. view more (2006-03-07)
National Physical Laboratory Stages Unique On-Line Experiments
Does your computer’s clock always run slow? How good are human beings at estimating? How much does gravity vary over the globe? With your help we are attempting to find answers to these questions as part of a huge on-line Web event to celebrate World Metrology Day 2001, Sunday 20th May. This is the first time NPL have attempted such a... view more... (2001-05-18)
A resetting signal keeps circadian rhythm on track in Drosophila fruit flies
A Brandeis University study published this week in Nature shows for the first time that a molecular signal maintains coherence among brain clock cells that regulate daily activity of Drosophila melanogaster (fruit flies). view more (2005-11-10)
Resistance exercise resets the body clock
Resistance exercise may directly reset the body clocks in skeletal muscle, according to research published in Genome Biology this week. This result may partly explain how exercising early in the day helps jet-lagged bodies readjust to their new time zone. Many processes in the body vary in a 24-hour rhythm called the circadian rhythm. These... view more... (2003-09-24)
Novel connection found between biological clock and cancer
Dartmouth Medical School geneticists have discovered that DNA damage resets the cellular circadian clock, suggesting links among circadian timing, the cycle of cell division, and the propensity for cancer. view more (2006-06-30)
Optical atomic clock becomes portable
You imagine a clock to be different - yet the optical table with its many complicated set-ups really is one. Optical clocks like the strontium clock in the Physikalisch-Technische Bundesanstalt (PTB) in Braunschweig could be the atomic clocks of the future; some of them though are already ten times more precise and stable than the best primary... view more...

Another reason to avoid high-fat diet -- it can disrupt our biological clock
Indulgence in a high-fat diet can not only lead to overweight because of excessive calorie intake, but also can affect the balance of circadian rhythms - everyone's 24-hour biological clock, Hebrew University of Jerusalem researchers have shown. view more (2008-12-29)
Phase of clock gene expression in human leukocytes correlates with habitual sleep timing
The phase of clock gene expression in leukocytes, assessed in the absence of the masking effects of light-dark and sleep-wake cycles, correlates with habitual sleep timing, according to a study published in the May 1 issue of the journal SLEEP. view more (2008-05-01)
First molecular evidence of body's internal clock in controlling blood pressure
It has been known for decades that heart attacks and strokes occur most frequently in the early-morning hours. Now, researchers at the University of Pennsylvania School of Medicine have provided the first evidence for the role of our body's internal molecular clock in controlling blood pressure and a mechanism by which this occurs. view more (2007-02-20)
Faulty body clock may make kids bipolar
Malfunctioning circadian clock genes may be responsible for bipolar disorder in children. Researchers writing in the open access journal BMC Psychiatry found four versions of the regulatory gene RORB that were associated with pediatric bipolar disorder. view more (2009-11-12)
Clock molecule's sensitivity to lithium sheds light on bipolar disorder
Researchers at the University of Pennsylvania School of Medicine discovered that a key receptor protein is a critical component of the internal molecular clock in mammals. What's more, this molecule -called Rev-erb- is sensitive to lithium and may help shed light on circadian rhythm disorders, including bipolar disorder. view more (2006-02-17)
Feeling sleepy is all in your genes
Genes responsible for our 24 hour body clock influence not only the timing of sleep, but also appear to be central to the actual restorative process of sleep, according to research published in the online open access journal BMC Neuroscience. view more (2007-10-18)
Hebrew University, US scientists find clue to mystery of biological clock
How does our biological system know that it is supposed to operate on a 24-hour cycle? Scientists at the Hebrew University of Jerusalem have discovered that a tiny molecule holds the clue to the mystery. view more (2009-11-30)
Flowers to Order
How do growers ensure their Poinsettias are ready for Christmas or their roses for Valentine’s Day? Professor Andrew Millar (Warwick University) will present current work on Thursday 3 April (in session P9.9) which could help breeders to schedule their crops more accurately. Like most organisms, plants possess a ‘clock’ which... view more... (2003-03-31)
Gene controlling circadian rhythms linked to drug addiction, UT Southwestern researchers find
The gene that regulates the body's main biological clocks also may play a pivotal role in drug addiction, researchers at UT Southwestern Medical Center have found. view more (2005-06-14)
